bors db3e99bbab Auto merge of #150605 - RalfJung:fallback-intrinsic-skip, r=mati865 
skip codegen for intrinsics with big fallback bodies if backend does not need them

This hopefully fixes the perf regression from https://github.com/rust-lang/rust/pull/148478. I only added the intrinsics with big fallback bodies to the list; it doesn't seem worth the effort of going through the entire list.

Fixes https://github.com/rust-lang/rust/issues/149945

README.md

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
